Discalimer: I don't own D. Gray Man or any of it's characters.
Anyways, I'll just inform you so it won't be confusing. I had a hard time deciding what to do or how to describe it since they swapped bodies. I just decided to call them by their names and italicize it. So those italicized names indicate that they're the real ones.
"FUCK!" Kanda inside Lenalee cursed.
"Calm down, Kanda." Lenalee said, "There's got to be some explanation."
"Do you think it's Innocence?" Allen asked, "Though I don't remember touching or being near a fragment during this train ride."
"Or it could be…" Lavi trailed, "Do you think Komui has something to do with this?"
"Now that you mentioned it, Allen- I mean Lavi, He did offer me a coffee before I left." Lenalee wondered.
"For some reason I feel weird." Lavi said, "It's really strange when I'm talking to someone who looks exactly like me- no I'm talking to someone else inside my body. It makes me feel crazy, you know? To find yourself talking to yourself. You get me, right?"
"I feel awkward listening and watching myself from here." Allen murmured.
"I feel weirder wearing fucking skirts here." Kanda grumbled. Everyone sweatdropped at this and silently pitied Kanda- though they won't say it because they didn't want to be slice by Mu- wait, let me change that- they didn't want to be kicked by Dark boots and Lenalee wouldn't enjoy taking hits from her own Innocence.
The atmosphere just went awkward as they sat there in silence.
Suddenly, Kanda stood up with a huff.
"Where are you going, Lena- um, Kanda?" Lavi asked.
"Toilet." The hot-headed-swordsman- now-turned-into-a-cute-girl said.
"Oh, okay." Stupid-rabbit-now-inside-beansprout's body grinned.
"No, wait! Don't go!" Lenalee paled as she blocked Kanda's path, "You can't go!"
Kanda tried to push Lenalee away but since he was in a female's body and Lavi body was physically stronger than Lenalee's - Lenalee managed to stop him. Angered, Kanda scowled- though it looked more like a pout in Lenalee's face, "What!? I can't stand it. Move or I'll use your own Innocence against you!"
"No, No, No, NO, NO, NO, NO!" Lenalee shrieked, "I can't let you!"
Allen winced at Lavi's high-pitched voice. Jeez, With Lenalee's shrieking and Lavi's already squeaky voice mixed- it really hurts. And he observed that Kanda really has sensitive ears.
If his ears were so good, why wouldn't he notice us whenever we call him? That arrogant bastard!", Allen though bitterly, "Lav- Lenalee, why can't Le- ugh, Kanda go to the toilet?"
"Don't you get it!?" Lenalee shrieked as she blushed- oh, Lavi looks slightly cute if he blushed.
It took them a few seconds to finally understand what Lenalee meant and at this they blushed. Kanda's angry scowl (or pout) turned into a blush.
"T-T-Then how do you expect me to pee?" Kanda uncharacteristically stuttered, though it seemed normal in Lenalee's face and voice, "Wait, how about I'll close my eyes and you remove the undergarments yourself?"
"I can't do that, Kanda!" Lenalee said, "I'm in Lavi's body now so basically I'm male. I can't enter the female's restroom!"
"How about you close your eyes, Yuu." Lavi suggested, "And don't look down while you're in there."
"I'll try." Kanda's eye twitched as he left the compartment.
Then all of a sudden, Lenalee paled.
"What's wrong, Lena?" Lavi asked- not mistaking her name.
"This is bad." Lenalee's eyes (or, rather, eye) started to swirl, "I think I need to go to the toilet too. What should I do!?"
Back to HQ- With Komui and company
"Chief, I can't contact them" Reever said.
" LENALEE!" Komui exaggeratedly cried on his desk as he stained the papers covering his desk with his tears, "My precious Lenalee! The octopus inside Lenalee's body must be ruining her innocence!"
"Chief! Calm down!" Revver massaged his temples as he sighed tiringly, "Why don't you just start working with an antidote?"
"Good idea! Well then, I'm leaving! I'm counting everything on you!"
"That lazy guy- leaving all the work to us." Reever sighed but then his face was filled with horror then to sadness then anger as he stared at the papers on the desk, "And now he's making me repeat what I already finished!"
Back to the exorcists
They had finally arrived on their destination. They were in a village on the outskirts of France.
"Let's get this damn mission finished as quickly as possible." Kanda grumbled, "We need to go to the Headquarters as quick as possible to reverse this stupidity."
The rest quietly agreed as they walked through the village, looking left and right to find something unusual. But, unfortunately for them, everything seemed normal.
They met with a finder before they reserved three rooms. One for Lenalee, One for Kanda and then Lavi and Allen were fine sleeping in the same room. They just decided to rent a room with two beds.
They just placed their things there before they decided to observe the area for a little bit. Right after they went out of the hotel, Allen's eye activated as Lavi felt faint presence of Akuma- it was near the village but it wasn't inside.
Lavi notified the others before they ran towards the akuma. It's better to fight it when it's still not inside the village so it won't hurt the villagers as cause a commotion. As for Kanda, he just didn't want distraction and he knew those villagers would be a pain in the ass.
The moment they spotted Akuma, they activated their Innocence- or rather, they activated not their Innocence but their companion's. And that's when they met trouble.
As Kanda used Dark Boots- he wasn't accustomed to fighting using his legs and with a skirt. He mentally noted to steal some pants to the beansprout since his size would be the closest to Lenalee. There's no way he's going to tell the beansprout- or rather the rabbit that he needed help. The toilet problem was annoying as it is- he was h=just thankful that Lenalee didn't have a period at the moment.
Just when he was about to leap- he didn't expect to go that high. He was literally up there. He didn't even know how control it. He used to remember how Lenalee could somewhat fly and he was intending to do it. He kick akumas but he can't seem to hit one of them. His timing sucked- the akuma was slow and he was going too fast. But despite his advantages- he didn't' how to FUCKING control these stupid boots.
"How the hell could she fight with these heels?" Kanda wondered, "Plus, they're unbelievably heavy."
As he charged straight this time, he gained a little control and he was able to kill an akuma- but he didn't know that he boosted the boots level 2 and directly hit 3 akumas by passing through them before he landed a direct kick to Allen's face. Fortunately, it wasn't as strong as how he killed those akumas but it hurt, nonetheless.
Allen's nose was bleeding as those heels left a mark on his face.
"That's harsh, Yuu-chan!" Lavi faked a cry.
"Don't call me that!" Kanda growled.
Lavi seemed to have a hard time with Allen's innocence but it wasn't as bad as Kanda. He had always observed others as well as he observed Allen and so he just did the exact thing he remembered Allen do. But there was a difference in a parasitic and equipment and Lavi was adjusting with that. He was not used to have an arm like Allen.
He could only use Cross Grave. He didn't know how to use Crown Clown. He inwardly cursed. There were only Level one but they seemed to have a hard time. They were at a disadvantage. Lavi never voiced it out but he sometimes felt dizzy. He also went silent for that train ride when he saw a strange reflection. He wondered if Allen sees these every day. He was closing Allen's left eye as he fought. He didn't like what he would see if he opens the other eye.
Lenalee was using the hammer with ease. She just wacked some akumas here and there but she didn't use any seals. She could only hope that there were only level ones here. She didn't really know how to use Lavi's innocence. Allen seemed to be fine with Kanda's sword. It was lighter compared to his Sword of Exorcism but it was a sword nonetheless and he had knowledge on how to handle a sword.
It seemed that Kanda was the one who had the most trouble here since he had the most troublesome body. Being the opposite gender, wearing short skirts, fighting with heels and etc.
Right after the akumas have ceased, Lavi opened the left eye to see if there were any more akumas but found that there were none left. The four just decided to go back to the hotel and call it a day.
I hope you understood what I was trying to write. =.= Sorry if some parts confused you.
